- DB introspection tests: introduce local RawDb alias for casts
that poke into the private .db handle.
- IPC handler tests: introduce IpcHandler alias matching the
registerHandle signature (event + unknown args).
- selective-ipc / session-management: narrow handler and data
params to unknown or the minimum shape the code reads.
- 10 tests covering worker crash detection, lock release, agent reset
- Session handoff markdown generation with real DB
- Context preservation (D-02): agent assignment retained after crash
- DB consistency verification: no running runs/agents, no orphaned locks
- Multiple concurrent runs all interrupted on crash
- Uses real AppDatabase with temp dirs, gemini_local connector
